RECEPTACLE.

Specification of Letters Patent.

Patented Feb. '7, 1911.

Application filed November 9, 1909. Serial No. 527,008.

To all whom t may concern.'

Be it known that I, MATTHEW GRAY, a subject of the King of GreatBritain, residing at Fernholme, I'Iolderness Road, in the city andcounty of Kingston-upon-Iflull, England, have invented new and usefulImprovements in Receptacles, of which the following is a specification.

This invention consists in a boX, canister, or other similar receptaclefor semi-liquids, pastes, powders and the like having one or more slitsor other suitable apertures formed in the receptacle or in the closurethereof, the said aperture or apertures being normally closed by theelasticity of the material from which the receptacle or closure is made,but which open when the closure or a suitable portion of the receptacleis pressed inward and allow a certain portion of the contents of thereceptacle to eXude or pass through the said aperture or apertures whenrequired for use.

My invention is illustrated by the accompanying drawings in which Figurel is a plan of a receptacle con structed according` to this invention.Fig. 2 is cross section of the same when full. Fig. 3 is cross sectionof the same when partially emptied of its contents. Fig. 4 is a plan ofa receptacle constructed according to this invention having apertures inthe closure thereof. Fig. 5 is section of the same across the slits.Fig. 6 is section of the same through the slits. Fig. 7 is a plan of areceptacle constructed according to this invention having threeapertures in the closure thereof. Fig. 8 is cross section of the same.Fig. 9 is a section of same through the slits. Fig. 10 is cross sectionof another form of receptacle constructed according to this invention.

The same letters denote the same parts throughout.

According to this invention I form the receptacle a and the closurethereof as shown in all the iigures by raising or stamping from sheetmetal, such as tin plate, or the receptacle and closure may be made fromany other suitable material such as Celluloid, vulcanite and the like,so long as the slitted portion thereof is of a springy or elasticnature.

As shown by FigsL l, 2 and 3, the receptacle a and the closure b aremade from sheet metal, the receptacle a being provided with a groove cin which is formed a slit CZ. The closure o is made to slide in thereceptacle tightly so as to prevent the escape of the contents from, andas much as possible access of air to, the receptacle.

lVhen the receptacle is full the closure Z) is in the position shown byFigs. 2 and 10, and supposing the contents to be paste black lead, bootpolish, polish for linoleum, parquet flooring polish, or other pastes orviscous substances, the contents may be eX- tracted in the desiredquantity when required for use by placing the receptacle on a table orfloor with the closure b downward as shown by Figs. 2 and 3 or upward asshown by Figs. 4 to 1() and pressing on the slitted portion with a brushor cloth, the pressure causing the slit Z to open and allow a smallquantity of the contents to exude on to the brush or cloth. The closureb in all cases recedes into the receptacle as the contents thereof areremoved, as is clearly shown by the drawings.

'Ihe aperture (Z is hermetically sealed when the receptacle and itscontents are ready for sale by means of a suitable varnish and in somecases by the manufacturers or retailers label.

vWhen in use for goods other than powders the aperture cl is sealedafter a portion of the contents has from time to time been removed bythe small quantity of the contents which remains in the groove c andaperture (Z, more particularly in the case of substances which containvolatile ingredients, as the evaporation of the said volatileingredients causes a film of solid material to eifectually seal theaperture and prevents 'further evaporation of the volatile ingredients.In such cases the point of contact between the receptacle and itsclosure is also similarly sealed.

As shown by Figs. 4, 5, 6, 7, 8, 9 and 10 the slits or other aperturesare formed in the closure b instead of in the receptacle a, the closureshown by Figs. 4, 5 and 6 having two grooves and slits or otherapertures therein, but the closure shown by Figs. 7, 8 and 9 is providedwith three grooves and apertures. The contents of the receptacles inwhich apertures are formed in the closure are caused to exude bypressing the closure inward.

In all cases to prevent waste of the contents the top or bottom of thereceptacle and the inner portion of the closure may be made of similarcontour as shown. The contour of that portion in Which the slits orother apertures are formed must be such that normally the apertures areclosed, but that pressure on the said portion causes the said aperturesto open to allow the contents of the receptacle to eXude or pass asrequired fer use.

If the receptacle is made with a depression in the bottom as shown byFig. 10 I provide means by which the groove in the closure and thedepression are kept in alinement, such as vertical grooves in thecircumference of the receptacle and closure for example.

Receptacles constructed according to this invention may be made of anysuitable size and shape and the apertures may be of any suitablekindalways provided that such apertures are normally closed and capableof being opened by pressing the portion of the receptacle or closurewhich contains the apertures inward.

Instead of forming one apertureas shown may form more than one slit ineach groove at any suitable part thereof.

hen using my receptacles for powders I may stiften the closure at oneside of the 3p; slit by forming a corrugation therein, in

which case the corrugated portion of the closure would remain rigid andpermit the other portion alone to be depressed toward the powder and ontilting` the receptacle the powder would be delivered on to thedepressed portion of the closure.

l. In a device of the class described, in combination, a receptaclemember and a closure member therefor, one of said members being formedof elastic material and having an aperture formed therein, theelasticity of the material maintaining the aperture normally closed, andpermitting the aperture to be opened when pressure is applied to thesaid member.

2. In a device of the class described, in Combination, a receptaclemember and a closure member therefor in telescopic relation to oneanother, one of said members being formed of elastic material and havingan aperture formed therein, the elasticity of the material maintainingthe aperture normally closed, and permitting the aperture to be openedWhen pressure is applied to the said member.
